烟的天使
该图中不是云，看上去有点像一个巨大的猫头鹰怪物，实际是一架C-17 Globemaster III 空军喷气式飞机五月份飞越大西洋上空时释放烟雾所形成的，这种烟雾和由此产生的模式有时也被称为烟的天使，图中烟的天使的圆眼睛，是飞机的机翼的螺旋桨造成的，被称为机翼的旋涡（文字翻译可能有出入，相见下英文介绍）
该飞机型号：C-17 Globemaster III Military Transport
C-17全球霸王III（Globemaster III，大陸翻譯：環球霸王）是美国麦道公司生产的戰略军用运输机，最新型的具有高度灵活性的战略军用运输机，适应于快速将部队部署到主要军事基地或者直接运送到前方基地的战略运输，必要时该飞机也可胜任战术运输和空投任务。这种固有的灵活性和性能帮助美军大为提高了全球空运调动部队的能力。C-17融战略和战术空运能力于一身，是目前世界上唯一可以同时适应战略、战术任务的运输机。（具体飞机介绍可以看http://zh.wikipedia.org/wiki/C-17%E8%BF%90%E8%BE%93%E6%9C%BA）
A Smoke Angel from Airplane Flares

Explanation: What type of cloud is that? It is not a naturally occurring one. Looking perhaps a bit like a gigantic owl monster, the cloud pictured above resulted from a series of flares released by an air force jet over the Atlantic Ocean in May. The jet that released the flares, a C-17 Globemaster III, is seen on the right. The flares release smoke and the resulting pattern is sometimes known as a smoke angel. The circular eyes of the above smoke angel are caused by air spiraling off the plane's wings and are known as wingtip vortices. |
